A smart key is the type of key your 2020 Chevrolet Spark uses. It contains a programmed transponder chip that communicates with your vehicle theft deterrent system to verify it is an authorized key before the engine will start. It also has 5 buttons for remote lock, unlock, and other functions depending on your trim level. Without proper programming and security relearn, even a perfectly cut key will not start your Chevrolet because the immobilizer will reject it.

Q: How much does the Chevrolet dealer charge vs a locksmith?

Chevy dealers typically charge 350 to 600 or more for a single key replacement. A Silverado owner was quoted more than 600 for a spare. A Bolt owner was pitched 495 per fob. A Traverse owner paid 295 for fobs and 80 for programming at the dealer. On the locksmith side, a Bolt EUV owner paid about 215 per aftermarket fob including cutting and programming. Batteries Plus did a 2023 Silverado fob for 171 total. Your 2020 Chevrolet Spark smart key runs 259 with us, fully programmed and tested on site.

Q: What is the FCC ID for the 2020 Chevrolet Spark key?

The FCC ID is HYQ4AA, HYQ4EA, LXP-T003. This is the identifier printed on the back of your key fob that tells us exactly which key your vehicle requires. It ensures we match the correct blank, chip frequency, and remote protocol so the key programs correctly on the first attempt. If you are comparing prices or shopping for a key online, the FCC ID is how you verify you are getting the right part for your specific Chevrolet.

Q: Do you offer a warranty on the key?

Yes. Every key we make comes with a warranty covering both the hardware and the programming. If anything goes wrong with the key, we stand behind it. One owner paid a locksmith over 700 for a fob that barely worked, with buttons that only responded every tenth press. That is not acceptable. A locksmith on Reddit said if they charge OEM prices, the key should work perfectly and they will fix it if it does not. We follow the same standard on every Chevy key we make.

2020 Chevrolet Spark Smart key Replacement - Fast, Affordable & Professional

Push-to-start all-keys-lost is the job that worries Chevy owners the most. No ignition slot, no way to turn a metal key. The car needs to wirelessly detect a programmed fob before it even wakes up. If that fob is gone, the car feels dead, but it isn't.

A camper at an RV park outside Camarillo had a 2020 Chevrolet Spark with push-to-start and zero keys. He was 40 minutes from town with no way to move the car. Everyone he asked said smart key all-keys-lost was dealer-only.

I drove to the park. Push-to-start AKL on Chevy is more involved because the body control module needs to be accessed directly and old key data needs to be cleared before new fobs can learn. I used my ACDP to pull the immobilizer data as a safety backup, then ran the AKL sequence through OBD. His smart fob, FCC ID HYQ4AA, was a 5-button proximity key.

His car started at an RV park with no dealer anywhere close. Total was around 259. The dealer route would have been 445 plus a long tow. Smart key AKL isn't dealer-only. It's tool-dependent. Right tools, current software, and it's a field job. He was pretty amazed it could all happen right there.

“Locked out on a weekend night and everyone else wanted $300+. EZ Car Keyz sent Roman late at night for much less. He worked for over an hour and did not give up until the door opened. They even made a new key on the spot.”

2020 Chevrolet Spark Pricing Questions

What it costs and what you get

Why is Chevrolet key replacement so expensive?▼

Modern Chevrolets use GM theft deterrent systems that require security relearn procedures and professional diagnostic tools. Older Passlock and PK3 systems need 30-minute relearn cycles. Newer push-to-start smart key systems require online security access through GM ACDelco TDS with paid subscriptions. A 3-day GDS2 license alone costs dealers 62 dollars. That subscription overhead, plus the fob, cutting, and programming labor, is why Chevy dealers quote 350 to 600 for a single key. The security technology is real, but the dealer markup does not have to be.
